Abstract: Une buse d'atomisation (40) conçue principalement pour pulvériser des produits destinés à l'agriculture, selon une répartition dimensionnelle étroite et régularisée des gouttelettes, est également capable de pulvériser en forme de cône ou d'éventail en continu de manière à répartir uniformément cette pulvérisation sur des cultures. La buse (40) est à même de fonctionner avec des arrivées d'air sous de faible pression, de l'ordre de 10 à 30 pouce de colonne d'eau. Un alésage central (44) destiné à l'arrivée d'air communique avec un collecteur d'air dans une rampe (12). Près du plan de sortie (46) du col se trouve un conduit d'admission (56) en communication avec le liquide à pulvériser, perpendiculaire à l'axe de l'alésage. Le plan de sortie (60) d'une buse d'émission (58) partant du conduit (56) et située sur l'axe de l'alésage se trouve en amont du plan de sortie (46) de l'alésage (44) de sorte que l'atomisation du liquide s'effectue dans l'alésage central (44), entre les deux plans de sortie (46, 60). Une paire de buses de mise en forme (66) est reliée à des alésages secondaires (68) qui, à leur tour, sont en communication avec le collecteur (12). Ces buses de mise en forme (66), qui sont dirigées perpendiculairement à l'axe de l'alésage central ainsi qu'au conduit d'admission (56), se trouvent en aval du plan de sortie (46) de l'alésage central (44). Les jets qui s'échappent desdites buses de mise en forme (66) donnent au cône de produit pulvérisé une configuration généralement en éventail. Etant donné que les jets de mise en forme sont toujours à la même pression que celle de l'air d'atomisation, la dispersion des gouttelettes à la sortie de la buse (40) est stable et la forme du produit pulvérisé reste constante au-dessus de la plage de pression de fonctionnement de l'appareil.

Title: Detection of nucleic acids by fluorescence quenching
Inventor: LINN C PRESTON
IPC: C12Q1/68
Filed: 1998-05-21
Granted: 2003-04-29
Abstract: A detector oligonucleotide having a sequence which forms an intramolecularly base-paired secondary structure is described for use in detecting nucleic acid target sequences and target sequence amplification. The detector oligonucleotide is further modified by linkage to two dyes which form a donor/acceptor dye pair. The two dyes are positioned on the detector oligonucleotide such that they are in close spatial proximity in the base-paired, folded secondary structure, thereby causing quenching of donor fluorescence. The detector oligonucleotide may optionally further comprise a restriction endonuclease recognition site (RERS) which remains partially or entirely single-stranded in the base-paired secondary structure. The RERS is flanked by the two dyes. In the presence of target, the base-paired secondary structure is unfolded or linearized, increasing the distance between the donor and acceptor dyes and causing a change in fluorescence of the donor and/or the acceptor. If an RERS is present, it is rendered double-stranded in the presence of target, allowing cleavage or nicking by a restriction endonuclease and separation of the two dyes onto separate nucleic acid fragments. This may further contribute to the magnitude of the change in fluorescence.

Abstract: An orphan condition is mitigated in a spread-spectrum communication system by determining when a remote unit (113) is likely to become an orphan (315) and adjusting remote unit (113) operating parameters (360) to force additional base stations (101, 102) to be added to the remote unit's (113) active set. In particular, when it is determined that a remote unit (113) is likely to become an orphan, T_ADD and T_COMP are adjusted so that the remote unit (113) is forced to add additional base stations (101, 102) to its active set.  Increasing the number of base stations (101, 102) that a remote unit (113) is communicating with greatly reduces the probability that the remote unit (113) will become an orphan.

Abstract: An image tracker (10) that tracks an object (16) targeted for engagement by a laser weapon (12).  The tracker (10) includes receiver optics (31) that receive radiation (30) from both a detected target (16) and a laser beam (14) incident thereon, and a polarizing beam splitter (44) that splits the radiation into a first beam of reflected laser radiation (46) and a second beam of detected target radiation (47).  The polarizing beam splitter (44) reflects the first beam of reflected laser radiation (46) in a first direction for imaging purposes and linearly polarizes the second beam of detected target radiation (47).  A beam polarizer (60) circularly polarizes the second beam of detected target radiation.  A micromirror array (66) reflects the circularly polarized detected target radiation back through the beam polarizer (60) to linearly polarize the second beam of detected target radiation (47).  Tracker electronics (33) adjust the reflectivity of the micromirror array (66) to ensure that the radiation incident on the array is at or below a predetermined irradiance threshold level.  Therefore, the reflected laser radiation does not affect the imaging of the targeted object. The linearly polarized detected target radiation beam is then reflected by the beam splitter (44) in a second direction for imaging purposes.  The tracker of the present invention enhances the probability of a target kill, as the actual laser beam hit spot (20) on the target is tracked relative to the target position.

Abstract: A turbogenerator/motor controller with a microprocessor based inverter having multiple modes of operation. To start the turbine, the inverter connects to and supplies fixed current, variable voltage, variable frequency, AC power to the permanent magnet turbogenerator/motor, driving the permanent magnet turbogenerator/motor as a motor to accelerate the gas turbine. During this acceleration, spark and fuel are introduced in the correct sequence, and self-sustaining gas turbine operating conditions are reached. The inverter is then disconnected from the permanent magnet generator/motor, reconfigured to a controlled 60 hertz mode, and then either supplies regulated 60 hertz three phase voltage to a stand alone load or phase locks to the utility, or to other like controllers, to operate as a supplement to the utility. In this mode of operation, the power for the inverter is derived from the permanent magnet generator/motor via high frequency rectifier bridges. The microprocessor monitors turbine conditions and controls fuel flow to the gas turbine combustor. The turbogenerator/motor controller can also have an energy storage and discharge system including an ancillary electric storage device, such as a battery, connected to the generator controller through control electronics. Electrical energy can flow from the ancillary electric storage device to the turbogenerator controller during start up and increasing load and vice versa during self-sustained operation of the turbogenerator. When utility power is unavailable, the ancillary electric storage device can provide the power required to start the turbogenerator. When a load transient occurs, the gas turbine engine and the ancillary electric storage device provide the power required to successfully meet the transient.

Abstract: An electric series circuit with plural loads such as light bulbs connected in series and plural solid state switching devices, with each switching device connected in parallel with one of the loads. Each switching device conducts current when the load that it is connected in parallel with does not conduct current because the load is burned out. The solid state switching means may be any device. with a breakthrough voltage which is high enough that it does not conduct when all of the loads conduct current normally. When one of the loads is burned out, that load does not conduct current and the entire line voltage appears across the switching means in parallel with the burned out load. The switching means breaks down. Accordingly, the switching means conducts current and current flows to the remaining loads. Accordingly, the remaining light bulbs in a string of light bulbs continue to light. The burned out load may be immediately detected and replaced. The switching means may be a sidac. Alternatively, a combination of an SCR and a zener diode controlling the gate of the SCR are also disclosed as the switching means. A diac may replace the zener diode.
